Cotton Candy Sugar Cookies

1 cup granulated sugar
1 cup powdered sugar
1 cup butter
1 cup vegetable oil
2 eggs
1 teaspoon vanilla
1 teaspoon salt
1 teaspoon cream of tartar
1 teaspoon baking soda
4-1/4 cups flour
Extra sugar for pressing cookies (Use red and green for Christmas cookies)

Preheat oven to 375 degrees F.
Cream together the granulated sugar, powdered sugar, butter, and cooking oil. Beat in eggs and vanilla.

Add dry ingredients, (the next four ingredients) and mix to incorporate. Roll dough into small balls about the size of a quarter. With a heavy bottomed crystal vase with a decorative bottom, or other cookie press, dip in sugar to coat well. Smash each ball of dough so they are spread out and flat. Leaving an imprint and sugar. Bake in a 375 degree oven for 10 minutes, until the edges just start to turn slightly brown. Do not bake too long. Cool sugar cookies on the baking sheet briefly then transfer to wire rack to cool the rest of the way.
